SWANSON,OF CEANSTON, RHODE ISLAND, ASSIGNOB '10 UNIVERSAL WIND- ING COMPANY, OFBOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS wmmne mom YApplication filed April 28,

This invention relates to improvements in winding machines for wmdmgcops, cones, coils, and other forms of packages from yarn,

thread and other strand materials.

In the following specification and claims the term package addition tocontrolling the winding operation, also regulates the point of deliveryof v the yarn with respect to the package being wound.

. Another object of the invention is to provide means for directing theam from the bobbin or other source of supp y to the package being woundwith its delivery point arranged to beshifted toward and away from thepackage in accordance with certain requirements.

Another object of the invention is to provide automatically-operatedmeans for maintaining the delivery point of the yarn remote'from thepackage during the winding operation and for shifting it into adjacentrelationship therewith when the op eration is arrested, whereby torender it more convenient to piece up the material or attach the end ofthe strand to the package.

Another object of the invention is to provide guiding-means across orover which the yarn from the supply leads with means operatedautomatically from the startingand stopping-mechanism of the machine toposition the guiding-means adjacent the package being wound before thewinding is started and to shift said guiding-means to a point remotefrom the package as the winding operation is commenced, thereafterreturning it to first position when the winding operation isarrested.

Another object of the invention is to provide a winding machine whereinthe supply 4 package, thetension-device and the. parts through or over.which the yarn feeds in delivering to the winding-mechanism may be isused in a general sense to indicate any form of product produced 1930:Serial in. 447,588.

located in close association with the package to facilitate threadingthe yarn therethrough, while at the same time maintaining the deliverypoint of the yarn from the supply in position remote from the package.

Another object of the invention is to provide means for shifting thedelivery point of the yarn toward and away from the package which isoperated automatically from a going element of the machine withoutattention on the part of the operator.

Another object of the invention is to provide an improvedstopping-mechanism for arresting the operation of the-machine.

Further objects of the improvement are set forth in the followinspecification which describes a preferred form of construction of ,the'invention, by way of example as illus-' trated in'the accompanyingdrawings. In the drawings:

' In practically all types of winding ma chines the supply for the yarn,whether a spool, bobbin, skein or other form offpacka'ge, must belocated relatively remote rom the package being wound, and usually thesupply is placed below the machine. It is of advantage, in fact quitenecessary as will later appear, to have a considerable length of yarnbetween its point of delivery from the supply and the pomt where it istaken up by the winding, but where the supply bobbin is placed at somedistance from the windingmechanism it is inconvenient of access to theoperator and necessitates reaching or stooping to piece up the ends orto doff and replenish the supply. Even though the supply bobbin itselfis placed nearthe package being wound the yarn must be carried to apoint remote from the winding mechanism before it can be led to thepackage, and this also necessitates reaching or stoop'ing' on the partof the operator to place the yarn in or around the guiding-means fromwhich it leads to the 7 package.

To overcome the inconvenience of locating the supply bobbin at adistance from the winding-mechanism the present invention contemplates adevice whereby the supply may be located in close association with thewinding-mechanism and theyarn carried over or through a guiding-meanswhich maintains the delivery point at proper distance from the packagebeing wound; the delivery point of the yarn being automaticallycontrolled to shift it away from the winding-mechanismas the winding isstarted and to replace it n position adjacent the winding-mechanism whenthe operation of the machine is arrested so as to facilitate the piecingup of broken ends and the attaching of the yarn to the package beingwound. The accompanying drawingsillustrate a winding machine of the.

. charactershown and described 'i'n United States Letters Patent No.1,749,355,'to F. A.

Reece, dated March 4, 1930; but it is'to be rom the bed or table 2 arebrackets or framemembers 4 which carry bearings. for the rotat-' ingdrive-shaft. 5 and other parts of the winding-mechanism. As herein shownthe driveshaft 5 is journaled in ballbearings 6 carried on the brackets4 and extends horizontally throughout the. length of. the gang machine.

- to serve as a drive for all of the units thereof.

The shaft 5 carries a series of drums or driverolls 7, only one of whichisshown in the present drawings, it being understood that a separaterollis unit.

The drive-roll 7 serves as the means for rotating the package by contactwith its surface and, in accordance with the invention of the patenthereinabove referred to, the roll provided "for each winding 7 is alsoconstituted as a means for traversing the yarn longitudinally of thepackage to deposit it in helical coils forming the layers which build uthe yarn mass. For this purpose the roll g, which may be termed atraverse-roll, is provided on its peripheral surface with a yarnreceiving and guiding groove .in which it is traveling to prevent it ifrom being diverted into the opposite helix of the groove, all as fullyset forth and illustrated in the patent hereinabove referred to.

As before indicated, the product of the machine may be a package of anypreferred form, the usual shape being cylindrical or I conical. The yarnis wound on a suitable receiver ,or core such as a aper tube or a woodenor fiber mandrel. is illustrated in the present drawings the machine isadapted for winding conical packages and for this purpose a cone-tube orreceiver 0 is rotatably mounted on a dead-spindle 10. To provide thatthe axis of the package may recede from the dri'veor traverse-roll 7during the growth in the windin the winding-spindle 10 is carried at theen of a swingin arm 11 pivoted on a horizontal stud 12 whic issupportedin 'a hub at the upper end of an upright 14 formed as a part ofthe frame-memher, or bracket 4. The arm 11 is constructed in two parts,with an outer extension 15 arranged to swivel in a hearing at the end ofthe main arm to adapt the winding-spindle 10 to assume an inclinedosition with respect to the surface of the roll The wooden tube oryarn-receiver C is held on the winding-spindle 10 by means of a latch 16i at its outer end.

In'machines of the present type the driveor traverse-roll 7 is. rotatedcontinuously and to arrest the winding operation the pack age is removedfrom contact with the roll through the operation of stopping-mechanismarranged as next described. Means are usually provided for actuatin thestoppingmechanlsm automatically w en the yarn breaks or its supply isexhausted, and. also a when the package reaches a predetermineddiameter. The arm 11 carrglmg the windingspindle 10 has a downwar'yextending leg 18, to the end of which is pivotally connected a bar orslide 20.v The rearward end of the bar 20 is formed with a slot 21engaged by a pin 22 fast in the end of the leg 18, and aspring 23 heldin a bore in the end of the bar acts on a plunger 24 hearing against thepin 22. Through this arrangement the connection between the bar 20 andthe arm 11 is cushioned to allow a slight play between the parts. Thebar 20 extends forwardly and downwardly and at its free end has a series1 pawl 26, whereby the ratchetteeth 25 on the at are successivelyengaged thereby. To arrest the winding 0 eration the bar 20 is drawnforward by roc ing the pawl 26 under the swinging action of the lever27.

Referring particularly to Fig. 4 of the drawings, the lever 27 ispivoted on studs 30 carried in hubs or bearings 31 formed on theframe-members 4. Pivoted to the free end of the lever 27 at 32 is ayoke-shaped dog 33, the lower-end of which is adapted to make contactwith a cam-shaped hunter 35 held fast on a shaft 36 and continuouslyrotated in the direction indicatedby the arrow. The shaft 36 isjournaled in bearings 37 in the frame-members 4 and may be connected bygearing or otherwise to be driven with or from the traverse-roll shaft 5at a much slower rate of speed.

The lever 27 is substantially U-shaped,

v having op osite forwardly-extendin arms 29 I connected y a late 38which norma y stands in substantia y vertical position, as illus- 35trated in Fig. 2, and serves as a thread-guard with its upper end infront of the traverseroll 7. Referring to Fig. 1 of the drawings, ears39 project forwardly from the plate 38 to provide bearings for a wirethread-bail 40 of inverted U-shape. The ends of the legs of the wirebail 40 are bent around at 41 to form bearings encircling pins 42 driventhrough the sides of the lugs 39. Extending from one of the legs of'thebail is a tail-piece 43 which is adapted to strike against a shoulder44, see Fig. 4, between the lugs to act as a stop to limit the forwardtilting action of the bail. The thread-bail. 40 has a cross-bar 45 overwhich the yarn 3 leads to the grooves 8 in the traverse-roll 7 asillustrated in Fig. 2, and when the strand breaks or its supply isexhausted the bar tilts forward under the action of a lever 48.

The lever 48 is pivoted on the pin 42 ad by a box-like casing-49projecting from the front of the plate or threadard 38. The right-handleg of the thread-bail 40 has an it to strike against the rearward edgeof t e lever 48, whereby when the lower end of the lever is swun to theright, as viewed in Fig. 2, it will roc the.upper end of the threadbailoutwardly, this motion being ermitted when the upper cross-bar 45 of theail is released by the breakage or running out of the yarn y. The lowerend of the lever 48 carries a pin 51, to which is connected a springhaving its opposite end anchored-to the dog 33 at 56. The spring 55 isnormally without tension, formin a link or connection between the lever48 and the dog 33 whereby to maintain the latter normally lifted awayfrom contact with the hunter-cam 35. When,

however, the thread-bail 40 is released from .the tension of the yarn yit allows the lever acts on the dog 33 'to rock the lever 27 and itspawl 26 whereby to slide the bar 20 to raise the package off from thedrive-roll 7 extension 50 bent around in an elbow to ada t to arrest thewinding operation; As the forward end of the lever 27 is rockeddownwardl the lower end of the lever 48 isv broug t against an inclinedabutment '57 on the side of the bracket 4. This latter engagement swingsthe lever 48 to stretch the spring 55 whereby the tension of the latterwill cause the do' .33 to be swung forwardly as soon as it is re easedfrom the banter-cam :A flat leaf-spring 60, fastened to the end Ilifting action of the dog 33 on its rearward end, see Fig. 4, itislocked in this position by means of a latching engagement with astarting-lever 65. The starting-lever 65 is Socured fastto a rod orrock-shaft 66 by means of a set-screw 67. The shaft 66 is rockable inbearing-hubs 68 on the opposite framemembers 4. The starting-lever 65reaches forwardly at the left-hand side of the winding-mechanism "withits bottom edge riding across a recessed edge 69 on the plate orthread-guard 38, see Fig. 1. The forward end of the starting-lever 65 isformed with a handle projecting outwardly beyond the thread-guard 38,and inwardly therefrom is a notched detent-shoulder 71 adapted to lockagainst the edge 69 of the plate 38 in the 'manner shown in Fig. 4 ofthe drawings.

he longer, downwardly-extending arm 79 of the lever is formed with a lugor from the side of the weight 82 is a abutment '80 adapted to strikeagainst the edge of a ivoted weight 82, one of the ele ments of t esizing-stop of the machine, to return this part to first position in themanner as later explained.

The sizing-stop, that is the means for arresting the winding operationwhen the package reaches the desired size, is constructed as nextdescribed. The sector-shaped weight 82 is rockable on the in 32 at theend of the lever 27, see 5, eing disposedat one side of the yoke o thedog 33. Projectilg normall bearing against the side of t e dog 33 toaapt it to rock the latter *down into position to be engaged by thebunter-cam 3 5 when the weight drops. The weight 82 s normallymaintained suspended in the position illustrated in Fig. 4 through themeans of a laterally movable latch 85. which extends rearwardly from itspivot. Referrm particularly to Fig. 5, the latch 85 is forme with ears86 which straddle a lug 87 projecting from the hub of the weight 82 witha pin 88 inserted therethrough to Not the latch to the weight. A plunger89 el'd in a lateral bore in the side of the weight 82 is I through aslot 98 in the arm. By loosening" ur d outwardly; by a spring 90 to bearag i nst the rear end or tail iece ofthe latch 85 whereb weight. finger91 is bent over from the side of the latch 85 to bear against the lug 87to limit the swinging movement-0f the latch under the action of thespring-plunger 89. The opposite free end of the latch 85 is bent atright angles to form a detent-catch 92 or latch proper which is normallyengaged beneath the underside of a ledge 94 projecting from the side of,an arm 95 fastened to the rack-bai'20. The upper part of the arm 95 fitsagainst the side ofthe bar 20 and is provided with a lip 96 overhangingthe topof the bar. The arm 95 is secured to the bar20' by means of abolt 97 passing the bolt 97 the arm 95 may be slid along the bar 20 toadjust its ledge 94 with ct to the detent 92 on the latch 85 so as to tie v I r I I the package into contact with the drive-roll 7.

to hold it in almement with the a bracket 100.

the sizing-stop to arrest the winding opera-- tion when the packagereaches any desired diameter. It will be understood that as the' bar 20slides outwardly across the dog 86 70 with the rising of'the arm 11,-ascause the growth in the winding, the led e 94 on the arm 95 willeventually ride off rom the end of the latch 85. This action releasesthe weight '82 to allow it to drop whereb its pin 83 acts against thedog- 33 to swing the latter into position to be engaged by the huntercam35. It is to be particularl noted that the or packages fromwhich theyarn is delivered to the winding is mounted oh ,a vertical frame orbracket 100 which also 5 pports the tension-device and the movab eyarn-guidin means for shifting the pointof delivery 0 the strand withrespect to the packa e bein wound. A bracket 100 is ot eacfi rovided ofthe winding units an as a convenient means of support therefor ahorizontal rod 101 is mounted in arms 102 clamped to the legs 3 of thegang machine. The bracket 100 comprises a member 103 having a hubheldfast on the rod 101 by set-screws 104; or other suitable means and.provided with arms 105 bolted to a flange 106 projecting from the sideof the vertical sion of the flange-106is formed with a slot 107 whichserves as a mounting for the supply-holder. The su ply-holder may be ofany suitable type an as herein shown consists of a bracket 110 fastenedto the an e 106 by means of bolts lll'passing through e slot 107. Throuh this arrangement the bracket 110 may ad'usted vertically to locate thebobbin or 0th carried'thereon in proper relation to the'tension-device,indicated generall at 120, whichv upper end 0 the frame or is carried atthe The supply-holder bracket 110 has a de-' pending arm 112 terminatinin ahub 113, on which is rotatably moun a spoked member 114'.

of the yarn therefrom, so that the operator ,is not required to stretchor stoop in tending the machine. o

Any suitable type of tension-device may be employed on the windingmachine and the present drawings illustrate a disk-tension of Fastenedto a lateral ear or flange 121 on the side of the frame 100 is a bracket122 provided with bearings 123 for a horizontal in or spindle 124, onwhich are mounted a pair of tensiondisks 125. The tension-disks 125 areof the usual concave-convex form arranged with their abutting faces inline with the axis of the bobbin B to adapt the yarn y to drawtherebetween. One 'ofthe disks 125 is held from lateral displacement andthe other is acted upon by a helical spring 126 on the spindle 124topress it toward the relatively fixed disk. Suitable weights 127,carried on a lever 128 which is pivotedto the tension bracket at 129,act to slide the spindle 124 to hold the spring against the side of thetension-disk to maintain the disks in yielding contact with the yarndrawing through the device.

' The tension-bracket 122 is formed with circular flanges130, see Fig.2, projecting outwardly in curved ears 131 which form a guideway fordirecting the yarn into position between the tension-disks; -Mounted onthe tension-bracket 122 below the tension-device is a slub-catcher 132for cleaning the yarn, and below this is a guide 133 through which theyarn draws to maintain it in line with the opening in the slub-catcher.A wire guide 134 beneath the guide 133 is provided to facilitate theoperation of threading the yarn into the guide 133 and through theslubcatcher 132. Extending between the flanges 130 of thetension-bracket 122 is a stud or pin 135 on which is mounted a roller136, pref:

erably of porcelain or other wear-resisting material. The yarn y drawsthrough the tension-device and around the porcelain roller anism whenthe winding operation is arrested and remote from the package during thewinding. For this purpose the yarn-gulding means or pin 140 is mountedon a weight or slide 141 adapted to be raised and lowered on the frame100. The slide 141 consists of a plate or block having a hole in itsupper end in which the pin 140 is secured by means of a set-screw 142.Projecting rearwardly from the slide 141 are studs 143 fitted to slidein a vertical slot 144 which extends from top to bottom of the frame 100The studs 143 have Washers 146 overlapping the sides of the slot 144 onthe rearward side of the frame 100, with cotter-pins 145 for holding theslide against the'front face of the frame. Throu h this arrangement theframe 100 forms a trac way with the slide 141 arranged to be moved 'upand down thereon. The downward movement of the slide 141 is limited bycontact of its lower edge with a washer 147 held in place by a bolt 148extending through the slot 144, the stop for the slide may be adpassesthrough the upper stud 143 and leads around a sheave or pulley 152pivoted on a pin 153 at the top of the frame 100. The cord 15 0 passesdown around a similar sheave 154 journaled on a pin 156 and thence drawsto the drum 155 with its end passed through a hole in the flange thereofand knotted to secure itthereto, see Fig. 6. The wind-up drum 155 isoperated automaticallv from the starting and stopping-mechanism of themachine to lower the slide. 141 when the windingmechanism starts tooperate, and to return the slide to its upper position when the windingoperation is arrested. The automatic means for controlling theoperationof the wind-up drum 155 is organized as next described.

Referring particularly to Fig. 6 of the drawings, the drum 155 isnormally free rotatively with respect to the continuously a against theside of the bunter-cam35 which is held fast on the shaft 36, and itsopposite end has an overhanging rim 157 provided on its side withratchet teeth 158. The ratchet teeth 158 are adapted to engage similarteeth 159 on .a ratchet-disk 160 which is freely rotatable on a sleeve161 secured fast to the shaft 36 by means of a set-screw 162. The

sleeve 161 carries a hub or collar 163 held means of a cord 150 whichiswound upon a drum 155 carried on the shaft 36. The cord 150 isattached to the cotter-pin 145 whichfast therewith by means of theset-screw 162 which passes through both elements. In the hub 163 .--areockets 164 holding helical springs 165 w ich bear against a disk orwasher-166 rotatable on the sleeve 161. Between the washer 166 and theratchet-disk 160 is a friction disk or washer 167, preferablyconstructed of fiber, leather or some similar material. Thesprings 165act to urge the washer 166 toward the disk 160 to provide frictionalcontact of the friction' sleeve 161 is a helical spring 170 coiledaround the shaft 36 with its opposite end bearing against the hub of thedrum 155. Normally, the spring 17 0 maintains the drum 155 slid to theright as viewed in Fi 6, with its hub bearing against the hub o thehunter-cam '35. The drum 155 is slid to the left against the tension ofthe spring 170, to engage its ratchet teeth 158 with the teeth 159 onthe disk 160 and through this connection the drum may be frictionallydriven from the hub 163.

The shifting of the drum 155 to clutch it with the friction drive iseffected bymeans of a clutch-lever 172 o erated from thestopping-mechanism of t e machine. Referring to Fig; 4, the clutch-lever172 is of elbowshape, having a flanged end 173 secured to the back ofthe plate or thread-guard 38 by means of screws 174. The free end of theclutch-lever 172 has an offset toe 175 which is beveled on its edge toadapt it to ride against a radial shoulder 176 on theflange 157 of thedrum 155 whereby to shift the drum to engage its teeth 158 with theteeth 159 on the ratchet-disk 160. This engagement is effected when thelever 27 is rocked into the osition illustrated in Fig. 4 to arrest thewin ing operation, the drum 155 being thereby clutched to the disk 160which is frictionally driven from the hub 163 to turn the drum to windup the cord 150. As the cord 150 is wound onto the drum 155 the slide141 is raised to the top of the frame or trackway 100 where its movementis arrested as the stud 143 comes against the end of the slot 144. Atthis juncture the ratchet on the drum 155 will still remain engaged withthe ratchet-disk 160, but the friction clutch between the disk and thehub 163 will allow slippage so that the drum will come tion, Figs. 7 and8 of the drawings illustrate a slide 177 having the tension devicemounted thereon to adapt it to be shifted from-an elevated position to apoint therebelow in delivering the yarn to the windingthe stud 178between the plates 17 9 and 180' and are pressed together by means of ahelical spring 184 held by a nut 185 screwed onto the end of the stud.

A- bracket 186 near the top of the frame 100 carries the ,slub-catcher132, guides 133 and 134 of the same arrangement as previously described.A pair of spaced hornshaped threading-guides 188 are also mounted on thebracket 186 for directing the yarn across a pin or roller 189, whence itleads over a roller 190 and down through the shiftable tension-device.

The method of operation of themachlne embodying the present invention isas next explained. Referring to Figs. and 2 of the drawings, to preparethe machlne for winding, a supply bobbin B is placed on one of thespindles 115 of the supply-holder and turned up into vertical position.The yarn y is drawn .ofl from the bobbin, led through the thread-guides134 and 133, thence passed through the slub-catcher 132 and drawn be-'tween the guards or ears 131 which direct it between the tension-disks125.

When the winding operation is arrested the slide 141 is suspended at theupper end of the guideway or frame 100 as illustrated in 3, and inthreading up the machine the yarn y is drawn rearwardly from thetensiondevice under the guiding-pin or stud 140 to attach its end to theyarn-receiver or conetube 0 which has previously beenmounted on thespindle 10 and secured in place by turning up the latch 16, see Fig. 1.

To start the winding operation the handle 70 is lifted to cause theupper arm 77 of the bell-crank lever 7 5 to be .raised to raise therack-bar 20 to free its teeth 25 from the dog or pawl 26. As therack-bar 20 is released arm 11 and its associated parts will rock thespindle 10 downwardl to place the surface of the yarn-receiver (d incontact with the continuously rotating driveor traverse-roll 7. As this;contact is accomplished the roll 7 starts rotation of the yarn-receiverC whereby to wind the yarn thereon. As the yarn commences to wind ontothe receiver 0 it is from this latter engagement the weight of thepicked up by the groove 8 in the roll 7 and thereby caused to betraversed back and forth longitudinally of the receiver to .deposit itin helical coils thereon as indicated at y in Fig. 1.

Prior to the starting of the machine the dog 33 has been carried out ofrange of the bunter-cam 35 under the action of the spring 55 in themanner as hereinafter explained. Upon the lifting of the starting-lever65its detent-shoulder 71 is released from the edge of the plate 38, seeFig. 4, so that the lever 27 is allowed to return into horizontalposition as shown in Fig. 2 under the action of the leaf-spring 60. Asthe lever 27 returns to first position the pawl 26 will engage theappropriate tooth 25 on the rack-bar 20 whereby to set thestopping-mechanism for operation in the manner as later explained.Meanwhile; the return motion of the lever. 27 swings the clutch-lever172 away from the flange 176 on the wind-up drum 155 whereby the spring170 acts to slide the latter to disengage its teeth 158 from the teeth159'on the ratchetdisk or clutch-member 160.

This release of the drum 155 takes place immediately the starting-lever65 is lifted-to start the winding operation and allows the drum'155 topay out the cord 150 to lower the slide 141 on its trackway on the frameor bracket 100. It has been stated that the yarn y is carried to theyarn-receiver C, or to the package being wound, beneath the guide-pin140 when the winding machine is of the operator. With the parts ofthemathreaded up and, consequently, as the slide 141 descends on itstrackway it will form a loop in the yarn as indicated in Fig. 2, the

strand passing from 'the tension-device 120 over the porcelain roll 136and down under the pin 140, whence it draws upwardly across the bar 45of the thread-bail 40. From the.

chine in the position as illustrated in Fig. 2 the yarn feeds throughthe tension-device 120 and thence is drawn downwardly around theguiding-pin 140 to stretch it out in a loop which provides aconsiderable length of yarn between this last delivery point and thepackage being wound.

When the yarn breaks or its supply is ex hausted the winding operationis arrested automatically through the operation of thestopping-mechanism as next explained.

The breakage of the strand or the running out of the yarn releases thethread-bail 40 to allow the lever 48 to swing to the right as viewed inFig. 2. The release of the lever 48 permits the dog 33, connectedthereto by the spring 55, to drop down into vertical position wherebyits end will be engaged with the eccentric periphery of the banter-cam35 j as the latter rotates with the shaft 36. The effect of thisengagement is to cause the dog 33 to be forced upwardly in the manner asindicated in Fig. 3 to tilt the rearward end of the lever 27 upwardlyand rock its forward end downwardly. This rocking action ofthe lever 27causes the pawl 26 carried thereby to draw the rack-bar 20 forwardlywhereby to swing the arm 11 upwardly to raise the package off from thedrive-roll 7 as shown in Fig. 3. As the forward end of the lever 27 isrocked downwardly the lower end of the lever 48 rides against theinclined face 57, which, as previously described, is formed as a part ofthe fixed frame-member 4, and thereby the lever 48 is swung outwardly tostretch the spring 55 connected to the dog 33. As the spring 55 isplaced under tension it acts to draw the dog 33 to the right, as viewedin Fig. 4, immediately the lower end of the latter is released fromthe'bunter-ca m 35 so as to prevent further movement of the dog from thecam. Previous to the release of the dog 33 the starting-lever 65, whichrides across the edge 69 of the plate 38, drops un der the action ofgravity to engage its detentshoulder 71 with the plate in the manner asillustrated in Fig. 4 to hold the lever 27 from I returning to firstposition. The parts of the stopping-mechanism are thus locked to retainthe rack-bar 20 in forward position to maintain the package lifted offfrom the drive-roll 7 until it is desired to again start the windingoperation.

As the lever 27 is rocked into the position illustrated in Figs. 3 and 4to effect the stopping of the machine the clutch-lever17 2 carriedthereby is moved to shift'the wind-up drum 155 to engage its clutch tocause it to be rotated from the shaft 36. Referring to Fig.

6, the beveled toe 175 of the clutch-lever 172 is carried against theflange ,176 to slide the drum 155 to the left against the tension of thespring 170. Through this action the teeth 158 onthe drum are broughtinto engagement with the teeth 159 on the ratchet-disk 160. It has beenexplained that the ratchetor clutch-disk 160 is driven frictionallythrough the medium of the washers 166 and 167 connecting it with thecontinuously rotating hub 163 carried by the sleeve 161. Consequently,

as the drum 155 is connected to the clutchdisk 160 it will be rotatedtherefrom in the direction indicated by the arrow in Fig. 6

whereby to Wind the cord 150 on its barrel.

against the end of the slot 144 to act as a stop. As the slide 141 israised on the frame package being wound. For t is reason the operator isnot required to stoop or reach downwardly in threading up the machine.

As the slide 141 comes to a stop at the top of the frame or bracket 100the rotation of the drum 155 is arrested as provided for by theslippagebetween the friction washer 167 v and the parts of the clutch engagingtherewith. Very little power is required to raise the slide 141 on itstrackwayand hence the slipping of the clutch as the rotation of the drum155 is arrested will not cause material wear on parts.

The arrestment of the, winding operation when the package reaches thedesired size is effected by the actuation of the stoppingmechanism fromthe sizin -stop previous y described. Referring to ig. 4, the arm 95 isadjusted along the rack-bar so that the ledge 94; on its lower end willride off from the detent '92 of the latch ,85 when the package reachesthe predetermined size. As the latch 85 is released-from the ledge 94 itallows the weight 82 to drop, whereby its pin 83' swings the dog 33 downinto positlon to be engaged and acted upon by the banter-cam 35. Theengagement of the dog 33 with the bunter-cam 35 then effects thestopping of the machine in precisely the same manner as above describedas the various instrumentalities perform their several functions; thedrum- 155 being clutched to the shaft 36 to cause it to wind up the cord150 to raise the slide 141 to the top of the frame 100.

In returning the parts of the sizing-stop to first position after theaction of the stopping-mechanism the lifting of the starting leverrocksthe bell-crank lever to cause the lug on its arm 79 to swing the weight82 upwardly to again engage the latch 85 with the ledge 94 .on the arm95 in the manner as previously explained.

In the modified form of the invention as illustrated in Figs. 7 and 8the operation of the parts issubstantially the same as above described.That is to say, under the action of the stopping-mechanism the drum 155is clutched to the shaft 36 to cause it to wind up the cord 150 to raisethe slide 177 to the top of the frame 100. On the other hand, uponstarting the machine the, clutch is released to free the drum 155 tocause it to pay out the cord 150 to lower the slide 177 to the positionillustrated in Figs. 7 and 8. The raising of the slide shifts thetension-device 180 upwardly into accessible location when the winding 0ration is arrested, whereby to facilitate th threading of the yarn intoplace therein; and the lowering of the tensiondevice carries thedelivery point of the yarn a'wa from the package being wound as the winin operation is started.

It wi be observed from the foregoing that the present invention providesan improved construction of stopping-mechanism for winding machineshaving means associated therewith and operated automatically therefromto adjust the oint of delivery of the am with respect to t e packagebeing wound. hrough this arrangement the supply bobbin from which theyarn delivers and the slabcatcher, tension-device and other placedwithin convenient reach to relieve the operator from the necessity forstooping and reaching in tending the machine. For this reason themachine can be tended with less 1 efiort and fatigue on the part of theoperatorv and with a saving of time which results in ing, one advantagebeing that when a break occurs, near the supply, as is usually the case,the broken end will not run into the winding before the rotation of thepackage is arrested. For this reason the broken end may be more readilyrecovered. As another advantage the provision of a relatively longlength of free yarn between the delivery arts through which the yarnmust be threade are point and the traverse-mechanism tends to revent thestrand from jumpin out or be- 7 mg dislodged from the groove 8 111 thetravarse-r0117. The extended length of yarn also provides for easieraction duringthe traverse of the yarn, since it is not required tomake,.'

an abrupt bend in the strand at the delivery point when the direction ofits traverse is reversed. v
